For the past two or three weeks, I've had a marine injury that got worse before it got better. It didn't respond to antibiotics, and despite looking pretty gruesome at its worst, it didn't have many of the telltale signs of an infection (e.g. pain). It has been a full three weeks now, and after consulting with doctors in Honduras and the United States, the best guess is that it was a piece of foreign matter (most likely coral) lodged in my skin that my immune system simply did not like. It kept me out of the water for most of my final week on the island, and it kept me from doing a blackwater midnight dive, but I didn't manage one final dive before I left, with both Andy and José.
